AFS-9780 atomic fluorescence spectrometer

AFS-9780 atomic fluorescence spectrometer 

Introduction:

Instrument adopts precise injection pump control sample, sample into absolute accuracy can reach 1%, improve the stability of measurement instrument; A single point of configuration correlation coefficient of standard curve than peristalsis sample have significantly improved; Automatically dilute the accuracy is high, thus automatically dilute range of up to 200 times. And for the first time the tube valve instead of the expensive reversing valve, pipe valve is much lower than the cost of the reversing valve, and life is much higher than the reversing valve, greatly reduces the user's equipment maintenance costs. And reagents don't direct contact with the pipe valves, solved the reversing valve sample cross contamination problem. Sample injection into intermittent flow system has the characteristics of both the sample accurately fast sample and intermittent flow measurement, to the characteristics of the online cleaning

Features:

1. The new injection pump system, equipment, first add large peristaltic pump design in injection pump system, the advantages of both injection and intermittent flow.

2. Abandon the traditional directional control valve, all adopt the clip pipe valve, life for hundreds of thousands of times, the reagent does not contact valve, high reliability.

3. Optional 130 automatic sampler equipment can realize automatic operation and semi-automatic operation measure way.

4. Effective flood flow separation device, the reaction more fully, separation effect is good

5. Using intermittent flow patent technology, online cleaning, no sample waste and cross contamination

6. The use of advanced gas-liquid separation patent device, shielded Shi Yinglu atomization system

7. A new modular pneumatic device, a pressure protection and throttle device, which can realize real-time online control

8. The first four fixed lamp design, automatic identification element lamp, significantly improve the work efficiency

9. Have self-diagnosis function

10. Automatic ignition at low temperature

11. Diluted sample automatically

12. A single point of automatic configuration standard series
